Aim: Artificial nutrition, including tube feeding, continues to be given to dementia patients in numerous geriatric facilities in Japan. However, the clinical characteristics of patients receiving artificial nutrition have not been fully investigated. Therefore, we tried to evaluate the clinical features of those patients in this study. Methods: Various clinical characteristics of all inpatients at 18 of 20 psychiatric hospitals in Okayama Prefecture, Japan, with a percutaneous endoscopic gastrostomy tube, nasogastric tube, or total parenteral nutrition were evaluated. Results: Two hundred twenty ‐ one patients (5.4% of all inpatients) had been receiving artificial nutrition for more than 1 month, and 187 (130 women, 57 men; 84.6% of 221 patients) were fully investigated. The mean age was 78.3 years old, and the mean duration of artificial nutrition was 29.8 months. Eighty ‐ four patients (44.7% of 187 patients) were receiving artificial nutrition for more than 2 years. Patients with Alzheimer's disease (n = 78) formed the biggest group, schizophrenia (n = 37) the second, and vascular dementia (n = 26) the third. Conclusion: About one ‐ fifth of the subjects receiving artificial nutrition were in a vegetative state. More than a few patients with mental disorders, including schizophrenia, also received long ‐ term artificial nutrition. We should pay more attention to chronic dysphasia syndrome in mental disorders. [ABSTRACT FROM AUTHOR]

Aim: This study investigated changes in functional status in home‐dwelling stroke survivors 1–3 years after inpatient rehabilitation. It also examined the factors associated with longitudinal functional changes and health‐related quality of life. Methods: Survey evaluations were conducted at the homes of 27 stroke survivors. The Functional Independence Measure (FIM), Short Form 36, Frenchay Activities Index, and Hamilton Depression Rating Scale were used to assess functional status, quality of life, social activity, and depression symptoms, respectively. Results: From the time of discharge to follow‐up (mean: 2.1 ± 0.6 years), total FIM and motor FIM scores were mildly improved, and cognitive FIM score was significantly improved. On the Short Form 36, physical functioning, general health, and vitality scores were lower than norm‐based scores. Multiple regression analyses showed a positive association between change in motor FIM score and Frenchay Activities Index score and a negative association between change in cognitive FIM score and elapsed time after discharge. With regard to health‐related quality of life, motor FIM score was associated with the physical component summary, whereas age and Hamilton Depression Rating Scale score were associated with the mental component summary. Conclusion: Social participation was associated with long‐term improvement in activities of daily living, indicating that interventions targeting social function are important for maintaining and further improving activities of daily living in stroke survivors. Health‐related quality of life was correlated with activities of daily living and depression; therefore, interventions targeting these parameters are important in improving the quality of life of stroke survivors.

Background: In Japan, the number of dementia patients admitted to hospitals and other care facilities has been increasing and their hospital stays prolonged. Until now, there has been no study examining the differences between patients in psychiatric hospitals and other care facilities. Here we attempt a comparative analysis of characteristics of dementia patients in psychiatric hospitals and other types of facilities based on a nationwide survey. Method: A nationwide, cross‐sectional survey was conducted in 2009–2011. Questionnaires were sent to randomly selected facilities and asked about each facility's status as of September 2009 and about individuals with dementia residing in each facility during the 2008 fiscal year. The portion about individuals consisted of items to assess eligibility for the Long‐Term Care Insurance programme. Based on data from 6121 patients residing in seven different types of facilities, features of dementia patients in psychiatric hospitals and differences among facilities were analyzed. Results: There was a significant difference in average age, activities of daily living level, and dementia severity level among the seven types of facilities. The average age in all types of facilities, except for psychiatric hospitals, was higher than the national average life expectancy of 82.59 years. The results of the study revealed that in psychiatric hospitals the proportion of men, those aged <75 years, demented patients with severe behavioural and psychological symptoms of dementia, and those with frontotemporal dementia was significantly greater than in other types of facilities. In other Long‐Term Care Insurance care facilities, dementia patients >80 years and women accounted for 80% of all patients. Conclusion: Result showed that dementia patients in psychiatric hospitals had a higher proportion of men, younger age groups, and severe dementia than other types of facilities. These features contrast markedly with status of dementia patients in other Long‐Term Care Insurance care facilities. In order to facilitate dementia patients' early discharge from psychiatric hospitals to other care facilities or to home, further fulfilment care services corresponding to severe dementia and early‐onset dementia may be needed.

Background The purpose of the present study was to investigate the existence of microstructure abnormalities in the white matter circuit in stroke patients and its relationship to depressive episodes. To target the prevention of depression, we also investigated the relationship between lymphocyte subsets and cerebral abnormalities in patients. Methods Participants included 18 patients with acute ischemic stroke and 22 healthy control subjects. Diffusion tensor imaging was performed. Whole-brain voxel-based analysis was used to compare fractional anisotropy ( FA) between groups. Blood samples were obtained, and the lymphocyte subsets were evaluated using flow cytometry. Follow-up examinations were conducted on 12 patients at 6 months. Results FA was decreased in the bilateral anterior limb of the internal capsule in stroke patients. At the 6-month follow-up examination, there was a significant increase in FA, which was associated with a lower depression scale score. Patients showed a decreased percentage of circulated regulatory T lymphocytes, and the degree of reduction was related to the decrease in the FA value in the internal capsule. Conclusions FA reductions in the anterior limb of the internal capsule cause abnormality in the frontal-subcortical circuits and confer a biological vulnerability, which in combination with environmental stressors results in the onset of depression. Our findings also demonstrated the possibility of preventing post-stroke depression by targeting the role of regulatory T lymphocytes in brain tissue repair and regeneration after stroke.

Aim Although wandering is one of the major research focuses of the behavioural psychological symptoms of dementia, assessment of wandering has mostly relied on caregiver-administered questionnaires. The purpose of this study was to compare staff-administered Algase Wandering Scale outcomes with objective temporal and spatial movement indicators obtained from the Integrated Circuit ( IC) tag monitoring system. Methods Patients with dementia were recruited from a dementia care unit in Osaka, Japan in 2007. Primary nurses administered the Algase Wandering Scale, and the temporal and spatial movements of the subjects were monitored by the IC tag. Written informed consent was obtained from each subject's proxies. Results Nurses' assessments of wandering were in agreement with the IC tag outcomes only during the day shift. Spatial movements assessed by the staff did not reflect those measured by the IC tag. Conclusion This objective measurement of wandering showed the limitations in the assessment of spatial and temporal movement by the staff. [ABSTRACT FROM AUTHOR]

Background With the recent approval of several new drugs, pharmacological management of Alzheimer's disease has become more complicated in Japan. The efficacy and safety of increasing the dose of donepezil to 10 mg daily were assessed in an open-label study of patients with mild to moderate Alzheimer's disease who were showing a diminished response to 5 mg daily. Methods The subjects included 27 patients with mild to moderate probable Alzheimer's disease whose primary caregivers had confirmed progression of symptoms during treatment with donepezil 5 mg daily. The dose of donepezil was increased to 10 mg daily, and the Alzheimer's disease assessment scale-cognitive subscale ( Japanese version), Neuropsychiatric Inventory, and Zarit caregiver burden interview scores were compared before and after dose escalation. Adverse events were also investigated. Results Efficacy was evaluated in 24 patients; three dropped out because of adverse reactions. The Alzheimer's disease assessment scale score showed significant improvement after dose escalation of donepezil ( P = 0.006). The total score of the Neuropsychiatric Inventory and the Zarit score showed no significant changes. However, the anxiety score of the Neuropsychiatric Inventory showed a significant increase ( P = 0.028). Safety assessment revealed that the dropout rate was 11.1% and adverse reactions occurred in 40.7%. Nausea (29.6%) and loss of appetite (22.2%) were common adverse reactions. Conclusions Because cognitive function showed improvement after increasing the dose of donepezil, the dosage of this drug should probably be adjusted based on the overall severity of Alzheimer's disease as well as the progression of cognitive dysfunction.

Aim Brain deformations might prevent clinical symptoms from worsening in patients with idiopathic normal pressure hydrocephalus ( iNPH). We investigated the relationship between reversibility of brain morphology after shunt operations and preoperative clinical symptoms in iNPH patients. Methods Using head magnetic resonance images with voxel-based morphometry, we measured the cerebrospinal fluid volume in the combined areas of the lateral and third ventricles and Sylvian fissure (the volume of the ventricles and Sylvian fissure ( vVS)) and the volume of the subarachnoid space at high convexity and midline areas ( vHCM) before and 1 year after lumboperitoneal shunt operations in 12 patients with shunt-responsive iNPH. We used the ratio of normalized vVS to normalized vHCM ( nvVS/nvHCM) as an index of the severity of the brain deformation. The degree of reversibility of the brain morphology after the shunt operation was defined as the change ratio of the preoperative nvVS/nvHCM to the postoperative nvVS/nvHCM ( CR-nvVS/nvHCM). Higher CR-nvVS/nvHCM values indicated more improvement in the brain deformation. In addition, we rated the severity of the white matter lesions on the preoperative magnetic resonance images based on the Fazekas scale. Dependency in activities of daily living, gait and cognition were evaluated before and 1 year after the shunt operations. Results After the shunt operations, the nvVS/nvHCM and nvVS decreased significantly, and nvHCM increased significantly. The CR-nvVS/nvHCM negatively correlated with the preoperative severity of dependency in activities of daily living, gait and cognitive impairments. The CR-nvVS/nvHCM negatively correlated with the Fazekas scale, but not with age, duration of the disease and cerebrospinal fluid pressure. Conclusions Reversibility of brain morphology, which varied among iNPH patients, would prevent clinical symptoms from worsening in iNPH patients. The presence of white matter lesions reduced the degree of reversibility of the brain deformations in iNPH patients. [ABSTRACT FROM AUTHOR]

Background: This multicentre open-label trial examined the efficacy and safety of the traditional Japanese medicine, or Kampo medicine, yokukansan (YKS), for behavioural and psychological symptoms of dementia (BPSD) in patients with dementia with Lewy bodies. Methods: Sixty-three dementia with Lewy bodies patients with probable BPSD (M : W, 30 : 33; mean age, 78.2 ± 5.8 years) were enrolled and treated with YKS for 4 weeks. Results: Significant improvements in Neuropsychiatric Inventory scores (mean decrease, 12.5 points; P < 0.001) and Zarit Burden Interview-Japanese edition tests (mean decrease, 3.6 points; P= 0.024) were observed. In patients who consented to an assessment after 2 weeks of treatment, a time-dependent significant improvement was observed in the Neuropsychiatric Inventory score ( n= 23; mean decrease, 14.4; P < 0.001), each subscale, including delusions and hallucinations, the Zarit Burden Interview-Japanese edition ( n= 22; mean decrease, 8.2; P < 0.01) and the behavioural pathology in Alzheimer's disease insomnia subscale. The Mini-Mental State Examination and the Disability Assessment for Dementia (DAD) showed no significant change. Adverse events were observed in 11 (18%) patients. Three patients (5%) discontinued YKS due to adverse reactions, namely, spasticity and exacerbation of BPSD, edema, and nausea. Hypokalaemia (<3.5 mEq/L) was present in four patients (6%) at the study endpoint. Worsening of extrapyramidal symptoms was not observed. Conclusion: YKS improved BPSD in dementia with Lewy bodies patients and caregiver burden scores without deterioration in cognitive function. YKS is useful for the treatment of delusions and hallucinations in BPSD. [ABSTRACT FROM AUTHOR]

Aim: The aim of this study was to evaluate the reliability and validity of A Quick Test of Cognitive Speed (AQT) for detecting early-stage dementia in the elderly Japanese population. Methods: A total of 280 clinical participants (180 with mild Alzheimer's disease, 43 with amnestic mild cognitive impairment, 32 with non-amnestic mild cognitive impairment and 25 control subjects) and 22 community-dwelling elderly individuals without dementia were recruited. The Clinical Dementia Rating, the Mini-Mental State Examination, and AQT were administered to all participants. The Neurobehavioral Cognitive Status Examination was also administered to clinical participants. Results: The intraclass correlation coefficient for the test-retest reliability of colour-form naming time on AQT was 0.88 (95% CI, 0.74-0.95, P < 0.001). AQT colour-form naming time was significantly correlated with the Clinical Dementia Rating, the total score on the Mini-Mental State Examination, and the total score on the Neurobehavioral Cognitive Status Examination and most of its subscales. AQT colour-form naming time was significantly longer in elderly individuals with mild Alzheimer's disease, amnestic mild cognitive impairment, and non-amnestic mild cognitive impairment than in control subjects. The receiver operating characteristic curve analysis indicated that AQT colour-form naming time significantly distinguished subjects with early-stage dementia (mild Alzheimer's disease, amnestic mild cognitive impairment, and non-amnestic mild cognitive impairment) from controls. The area under the curve was estimated to be 0.88 (95%CI = 0.82-0.95). A cut-off of 71/72 seconds yielded the best sensitivity/specificity trade-off: sensitivity = 85% and specificity = 76%. Conclusions: AQT is a useful brief screening tool for detecting early-stage dementia in elderly Japanese individuals. [ABSTRACT FROM AUTHOR]

Aim: The number of elderly people with dementia in Japan is likely to increase as the population ages. In some areas in Tottori Prefecture, dementia-prevention classes have been conducted for several years. In the present study, we evaluated dementia-prevention classes in nine districts of Tottori Prefecture in terms of cognitive function, assessment by the leader and subjective evaluation by participants. Methods: The study's subjects included 112 community-dwelling elderly residents who were selected after a two-step screening. Data were collected according to the following four factors: (i) evaluation of cognitive function at the beginning and end of classes; (ii) the content of the classes; (iii) observations regarding the state of subjects; and (iv) participants' subjective evaluation obtained via a questionnaire distributed at the final class. Results: In terms of cognitive function among all subjects, scores significantly improved after the dementia-prevention classes. However, there were no significant cognitive improvements in the districts where programmes were biased towards a single category (e.g. systemic exercise, creative activities). Based on class leaders' assessments, subjects showed improved appearance and facial expression in later classes. Participants became more involved in the programmes, and their interests in others increased. In terms of their daily lives, subjects became more involved with others and more active after participating in the classes. Conclusions: Dementia-prevention classes improved not only cognitive function but also other aspects of daily life, as well. We thought it was important to evaluate both objective and subjective factors related to the classes. [ABSTRACT FROM AUTHOR]

Background Olfactory function is an important sensory perception function that helps us detect the smell of spoiled food, dirty clothing, and gas leaks. If ageing and Alzheimer's disease ( AD) are accompanied by a decline in olfactory function, this might reduce the ability to sense danger, placing the safety and hygiene of elderly people at risk. Methods Subjects in this study included 113 healthy subjects aged 20-89 years and 12 persons with AD aged 62-85 years. The healthy subjects were divided into three groups according to age: young-adult group (20-43 years), middle-adult group (45-69 years), and old-adult group (70-89 years). The Hasegawa Dementia Scale- Revised score of AD subjects ranged from 15 to 26. We developed and implemented an odour identification ability test and a situational judgement test using an odour stick to examine the impact of ageing and AD on olfactory function from the perspective of sensing danger. To examine the impact of mild AD on the olfactory function, we compared the scores between the AD group and the age-matched control group. Results The scores for the situational judgement and odour identification ability tests were significantly lower in an old-adult group than in the young-adult and middle-adult groups. A significant correlation was found between age and scores for both tests in the control group. The AD group exhibited significantly lower total scores on both tests compared with the age-matched controls. Conclusions These results suggest that ageing and mild AD may reduce the ability to identify odours and judge situations based on odours. [ABSTRACT FROM AUTHOR]
